qgis_calculatevectoroverlaps: QGIS algorithm - Overlap analysis

In JanCaha/r_package_qgis: An extension of package "qgisprocess" providing direct R functions for QGIS functions

QGIS algorithm - Overlap analysis

Description

QGIS Algorithm provided by QGIS (native c++) Overlap analysis (native:calculatevectoroverlaps). This algorithm calculates the area and percentage cover by which features from an input layer are overlapped by features from a selection of overlay layers. New attributes are added to the output layer reporting the total area of overlap and percentage of the input feature overlapped by each of the selected overlay layers.

Usage

qgis_calculatevectoroverlaps(
  INPUT = qgisprocess:::qgis_default_value(),
  LAYERS = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  GRID_SIZE = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT	source - Input layer. Path to a vector layer.
LAYERS	multilayer - Overlay layers. .
OUTPUT	sink - Overlap. Path for new vector layer.
GRID_SIZE	number - Grid size. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
...	further parameters passed to qgisprocess::qgis_run_algorithm()
.complete_output	logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.
.quiet	logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.
.messages	logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
